Advance your Alzheimer’s Disease Research with pTau217
Researchers worldwide are advancing AD research with ALZpath’s pTau217 antibody – a trusted reagent delivering sensitive, reliable detection across studies and collaborators.
ALZpath has developed a highly specific monoclonal antibody against phosphorylated tau at threonine 217 (pTau217). In immunoassays, that antibody functions as the capture antibody in a sandwich format [1]. This makes it ideally suited for ultra-sensitive detection of pTau217 in plasma and CSF.
The ALZpath antibody is licensed across multiple assay platforms, enabling broad translational and research access.
Note: ALZpath’s pTau217 antibody is a Research Use Only (RUO) reagent.
pTau217 Antibody Licensed Across Multiple Assay Platforms
Partner | Platform (example) | Status |
